In UTS, Key functions as a symbolic compression object: it helps route meaning through attention, memory, boundary, identity, action, or restoration depending on context.

3. Coherent Use

Key is coherent when its symbolic meaning remains auditable, scope-bound, and connected to real system behavior rather than performance alone.

4. Inversion Risk

Key becomes incoherent when the symbol replaces the meaning it was meant to carry, hides unresolved debt, creates false authority, or binds identity without repair capacity.

5. Restoration Use

Key can support restoration when it marks memory, boundary, closure, recommitment, or transition while remaining connected to material repair.

6. Canon Anchor

A symbol is coherent when its compressed meaning preserves boundary, auditability, compatibility, restoration, and identity integrity across time.
